4 Detailed function
4.1 Switch input DI
4.1.1 Switch input DI collection
Switch input DI to measure level signal or edge pulse signal (rising edge, falling edge). Support dry
node collection, support DI counting function, the maximum count is 65535 (the count is
automatically cleared when 65535 is exceeded).
The switch input DI supports three trigger modes: rising edge, falling edge, and level (the default
level trigger mode).
The clearing method supports automatic clearing and manual clearing (default automatic clearing).
4.1.2 Switch input DI filter parameters
When the switch inputs the DI to collect the signal, it needs to keep multiple sampling periods before
confirming. The filter parameter can be set from 1 to 16 (default 6 sampling periods). The DI filter
parameters can be set through the configuration software.

4.2 Switch output DO
4.2.1 Switch output DO description
Switch output DO, with level mode, pulse mode, follow mode (only follow DI). Using C-type relay output
(normally open + normally closed), the single-channel output supports a maximum load (contact capacity) of
30V/10A or 250V/10A.
Each DO output is designed with an output indicator (red LED indication) to indicate whether the output port
is on or off.
When the LED indicator light is on, it means the relay is closed (normally open and normally closed);
When the LED indicator is off, it means that the relay is not closed (normally open off, normally closed on).

4.2.2 Switch output DO mode setting
(1) Level mode
Output according to the level set by the user. The switching characteristics of the level mode are
similar to the function of a self-locking switch.
(2) Pulse mode
After the switch output DO is turned on, the set pulse width time (in ms) is maintained, and the
switch output DO is automatically turned off. The pulse width setting range is 50～65535 (default
50).
(3) Follow mode
After the user sets the follow mode, set the follow input terminal. The switch output DO
terminal is consistent with the DI input terminal.
Note: Multiple switch output DO terminals can be set to follow one DI input terminal, and one
switch output DO terminal can not be set to follow multiple DI input terminals.
4.3 Device address
4.3.1 Device address
Device address composition: hardware address + software offset address
Figure 4-3-1 Device address
The default device address is: 1 (hardware address 0 + software address 1 = device address 1).
Device address setting range: 1～247.
Hardware address: realized by the dial switch (5 digits) dial setting (the factory default is 0).
Software address: It is realized by the "offset address" set by the configuration tool software (the
factory default is 1).
For example:
If the hardware address is set to 5 and the software address is set to 113, the device address is 118.

Hardware address: The DIP switch can switch different hardware addresses, and the binary system
represents the 5-digit DIP switch.
The "5" direction indicates the high position, and the "1" direction indicates the low position. The
hardware address range can be adjusted from 0 to 31.
Hardware address dialing setting instructions:
Example 1: Set hardware address 0 (default), binary code.
4-3-3 Hardware address 0
Example 2: Set the hardware address to 8, binary code.

Example 3: Set hardware address 31, binary code.
314-3-4 Hardware address 8
The hardware address can be customized according to the actual situation. The setting method is
shown in the above example.
If multiple devices need to be connected to a single RS485 bus, only the hardware address is used. A
single bus can be connected to a maximum of 32 devices (just set the hardware address).
If you need more than 32 devices to connect to a single RS485 bus, you need to set the software
address (offset address) to realize a single bus to connect up to 247 devices.
After changing the address, you need to power off and restart the new address to take effect.
Note: For the following 3 products, the DIP switch is in the product shell. If the DIP switch is set, the
shell must be disassembled and then set.

4.3.3 Software address (offset address)
Software address: The user can make different settings according to the scene. The software address setting range is 1～
216 (device address: 1～247), and the default software address is 1.
After changing the address, you need to power off and restart the new address to take effect.
To change the software address, it needs to be realized through the configuration tool software, as shown in the figure:
